MACHINE For. nnncrmu' wrums or BRICK AND THE IKE.

Application filed February 2, 1924, Serial l lo. 690,160, and. in GreatBritain February lti, 1923.

This invention has reference to machines for erecting walls of brick andthe like and comprises improvements in the machine for this purpose setforth in my prior patent spec ifications Nos. 119,331 and 134,296.

The objectof'my. presentinvention is to provide a machine whereby thebuilding of walls can be more expeditiously accomplished.

According to this invention the improved anachine comprises, incombination, upright structures, a cross member (or members) extendingbetween and joining said upright structures, and brick laying vmechanismcarried by and adapted to travel along said cross member, or crossmembers, the combination being such that the brick laying mechanism canbe traversed to lay a course of bricks on each of four rectangular wallsin succession.

Preferably the improved machine comprises in combination, two uprightstructures adapted to travel on rails, a horizontal structure or memberjoining said vertical structures, brick laying mechanism carried by andarranged to travel along said horizontal structure or member, and meansfor traversing the apparatus on its rails. V The arrangement andconstruction of the machine is such that the said vertical structurecanbe traversed on rails laid on the outside-of two paralle'lwalls to bebuilt, the'brick laying mechanism laying a course of brick on one of thewalls during such movement, the brick laying mechanism then traversed onthe horizontal structure to lay a course onfthe one of the end walls,the structures th again traversed on their rails in the oppositedirection, a course of bricks being simultaneously laid on the otherwall parallel to the rails, and the brick laying mechanism againtraversed over the horizontal structure in the reverse direction th rebylaying a course of bricks on'the other end wall It will thus be seenthat a course of brick is laid on each of the four walls in succession,

after which the traversed member is raised to permit of the next courseto be laid.

My invention further consists in various improvements in the bricklaying mechanism and the features of construction which will behereafter described and pointed out in the claims.

In order that my invention will be properly .understood 1 have hereuntoappended seven explanatory sheets of drawings illustrating a preferredembodiment of my invention and operating mechanism therefor andwh'eren:Figure 1 is'an elevation of the machine, a part-- of the traversestructure being'shown broken away, but the length thereof willbe.

wheel controlled by manually of a relative rotary movement.

*Said frames 11 are provided with a number of fiat faces 13 each havingtwo spring actuated arms 14 for holding the bricks thereon.

The horizontally extending structure B is suspended at the four cornersby ropes 15 which at one'sid'e of the machine pass directly to a windingdrum 16 located at the upper end of the vertical structure A, while theropes supporting the other side of the structure pass over the pulleys17 at the upper end ofthe-structure A and thento the drum 16; I A squarevertical shat-t 18 extends irom endtoend of the vertical structure A andon vertically of each of said structures A, A is a square vertical shaft24 on each of which is a bevel wheel 25 also capable of a relative axialmovement but incapable ot a rotary movement thereon. The lower end of:each i of said shafts is provided with a bevel wheel 26in mesh with abevel wheel 27 on the axle of which is a spur wheel 28.

. The latter through an intermediate wheel 29, Figure 2, drives the spurwheel 30 which in turn meshes with the racks 31 laid parallel' and onthe outside of two walls to be built. I

In mesh with the bevel wheels 25 are the bevel wheels 32 carried at theextremities of a horizontally extending square shaft 83 which is drivenby gearing hereafter described. V r

wA mortar tank 34 is carried by the frame supporting the brick layingmechanism and which supplies mortar to the wall as the buildingproceeds. I V 1 The gearing'whereby the necessary move ment 1S impartedto spur wheel 8 to traverse thebrick laying. mechanism on the structure13, and to shaft 88 whereby the machine as a avhole can be moved on therails, and also the brick laying mechanism, will now be described. V I vA motor 35, see Figures 10 and 11, carried by a frame projecting fromthe carriage 6 drives through a train of gearing 86., 36 38 36, 36 and36 a shaft 37 on which are two loose bevel wheels 38 and38 A slid'ngclutch 889., controlled by the hand lever 38, is adapted to engage withand drive "either of said bevel wheels. A third bevel wheel 38 ontlie'shatt 39 is in mesh with wheels 38 and 38, the three togetherforming a reversing gear for the shaft 39 on which is also keyed thespur wheel 39? which through the intermediate gear'wheel 39 see Figureures 10 and 12.

13, drives the spur wheel '8 in meshwith the rack 5 and by which thebrick laying mechanism is traversed on the structure B.

Also mounted-0n the shaft 37 is a bevel wheel 40 which through bevelwheel 40 drives the shaft 40 On the latter is a double clutch member 41,41*, arranged toengage With either clutch members 42, 42 the bevel wheel42 loose on'the shaft 40". Saiddouble clutch member is operated by ahand lever 41 through the links 41. j

Those clutch members are so arranged that eitherfot' them can be broughtinto engagement with the corresponding clutch member on the bevelwheelbut they are'set one at 180 in advance of the other.

Said bevel wheel 42 drivesthrough a bevel wheel 44 a vertical shaft 44which at its lower end carries thespur Wheel 44 ,see Figures 1, 9,10 and13. The latter is in mesh with the large tooth wheel 44 loose on acasting 44- from which the brick laying mechanism secured to s issuspended. Also in mesh with this wheel 7 is the pinion on the verticalspindle 45, see Figure 4, which, through the bevel gear in 45 45 drivesthe horizontal shaft 46 on which is keyed the cam 47 by which the bricklaying mechanism is operated and which will be hereafterdescribed. 7

Also meshing with the spurwheel '36 is the spur wheel 48 on the shaft 48on which are the loose spur wheels 49 and 50, see Fig- Spur wheel 49gears directly with a spur wheel 49 on the transverse square shaft 33,

see also Figure 1, while spur wheel 50 is in mesh with the intermediatepinion 5O which in turn meshes with the spur wheel 5O on the saidsquaresha'ft. Both spur wheels 49 and 50 are capable of anaXial movementontheir shaft. Also on the shaft 48 is a clutch -51 controlled by lever51 and which can be operated to drive either of the spurwheels 49 or 50according on the direction in which it is de'siredtorotate the squareshaft 33. -'By such means the direction of travel of the machine on itsrails can be reversed as desired or by bringing the clutch to a neutralposition, the structure can be brought to rest.

The casting 44 see Figure 10, from which the brick laying mechanismissuspended is provided with a shoulder 44 which rests on thecorrespondingly shaped shoulder I44 of a ring 44 secured by lugs 44 tothe carriage 6. Said casting 44 is provided with four notches 44 seealso Figure 13 with one of which a latch 44 is normally in engagementand by which the casting 44 and bricklaying mechanism is prevented fromrotating under the action of the tooth ring 44;

Said latch is carried at the end of a rod 100, the upper end ofwhichis'connecte d to a By pulling this latter thebell crank can betomove vertically. 69 are guide rods se-' Lesa-27c operated to raise thelatch 44 clear of the notch 44 thereby permitting the rotation of thecasting 44 and brick layinginecli-anism with the tooth ring 44 throughan angle of 90, the latch entering the nextnotch and lOCkiIlg the wholein position.

The framework 9 for holding the columns 7 plates 53 notched as indicatedto accommodate the-bricks. The outer extremities of said plates arepivotally secured to the levers 54, 54 pivoted at 55, 55 respectively tothemachine frame.

One of said levers 54 is connected to a helical spring 56, while theother end'thereof abuts against an arm 57 pivoted to the machine frameat 57. Also pivotally secured to the machine frame at 58 is a bell cranklever 58 connected by means of a link .59 to the arm 57 Pivoted to themachine frame at 60 is an arm 60 which carries a roller 61 and which isloaded by the two helical springs 62 maintained under tension. seeFigures 3 and 4. To this arm is secured the two downwardly extendingrods 63 which are connected to the rod 64 the lowerextremity of which isconnected to an arm 65 'pivotally secured at 66 and connected by meansof a short link 67 to a frame or plunger 68 provided with fourprojections 69 and-arranged cured to the plunger and which slide inholes in guide blocks 69 carried by the cross bars 69.

On one of the rods (33 is a stop 70 which coacts with one of the arms 58of thebell crank lever 58. or frame of the brick laying mechanism isobtained through a pinion 70 on shaft 46, spur wheel 70, sprocket wheel'70", chain 70 and sprocket wheel 70, the latter being keyed brickretained thereby is about to be deposited on the wall. I The'mortar tank34 is arranged to supply mortar to the upper side of'the course ofbricks previously laid.

The operation of'th'e apparatus is as follows.

'Assume the brick laying apparatus to be travelling itSJIlCllCZLlBCl bythe arrow Figure 1.

W hen laying this course of bricks the motor is transmitting motionto'the spur wheel .8

which, as it is in mesh with the rack 5,

The rotation of the drum' deposits the bricksas formerly.

causes thecarriage 6 and brick layingmechanism to travel along thestructure B. Once every brick length traversed cam 47 permits the rods63 to descend under the action of the springs 62 .which results in theframe or plunger 68 carrying the projections 69 descending rapidly andknocking out the lowest bricks carried by the frame and deposit same onthe wall, the bars 72 simultaneously forc- 7 ing the arms holding suchbricks slightly apart. Simultaneously the descending rods permit the arm58 of the-bell crank lever to effect alike movement so that the arm 57moves outwards and the lever 54, 54 turn about their pivots all underthe action of the spring 56. This results in the notched arms co-actingsharply with and dislodging the lowest brick in each column, whichbricks fall on the frame 11 and are received bythe upper'spring loadedarms which are opened to receive them by the action of th-e rollers 71.

As'the cam rotates further the frame-or plunger (38 is raised and'theprojection 70 co -acts with the arm 58* to return same" to its upperposition, the'notch'ed plates 53 under the action of the spring 56 beingreturned to the position shown in Figure 6 thereby allow- -ing the pairof bricks supported thereby to fall on to the'plates52. In like manner,as the carriage 6 and brick laying device'moves along the wall, a pairof bricks is intermittently fed to the frame or drum and a'pair ofbricks simultaneously deposited on the wall." g 6 It will be understoodthat the spur wheel 8 must move the carriage 6 a distance equal to, onebrick length plus the thickness of a mortar joint while the cams 47makes exactly one revolution. 'lVhen the end of the wall is reachedclutch 38 is operated to bring the machineto rest and by meansof thelinks 102 and 103 the latch 44 is raised clear of the U notch with whichit is in engagement.

Here it would be explained that the resistance offered totherotation'of-the camshaft 46' is greater than that offered to therotation lie of the brick laying mechanism bodily so that w the casting44 then rotates withthe tooth ring 44 and carries'pinion 45 and bricklaying mechanism with same; a pawl engaging rotating in the reversedirection.

When the brick laying mechanism has been a ratchet wheel 103 'preventsthe cam shaft turned through an angle of 90 the latch en-,

gageswith the next notch thereby preventing further rotation. Clutch 51is then oper ated to drive the square transverse shaft 33.

This shaft drives through the bevel wheels machine as a unit along therails. During this movement @the brick laying mechanism 32, 25, 2 6, 27and spur wheels 28 and29 the spur wheels 50, which being in engagementwith the racks 31 on the rails 1 traverse the outof gear to bring thewhole structure to rest, the laying mechanism again moving.

the transverse square shaft and thereby move the apparatus bodily alongthe-rails, the brick a ine a J ara us de aositin a courseof bricks 1 a ta during its travel. At the end of this wall it is necessary to raisethe transverse structure .a distance equal to the height of a brick plusthe thickness of alayer of mortar. This is accomplished by an attendantmounting the platform 22 and operating the winding. gear 21 whereby theropes 15 are wound on the drum 16 and the wiole transverse structureraised to the requiredextent.

The brick laying apparatus is rotated through an angle of 90 but beforeproceeding to lay the next course it is necessary that the brick layingapparatus be moved dis tance equal to half a brick length beforecommencing to 'deposit'the second course. This is effected bywithdrawing the double clutch member 41, 41 to aneutral position and, asthebrick laying apparatus traverses the member 13, slipping it into theclutch member 4-2 or 42 which is half a revolution behind the memberpreviously in engagement. therewith. As shafts 39 and 40? rotate onerevolution per brick length, this results in the second course of bricksbeing laid in proper stag- .gcred relationship with the courseimmediately below.

In like manner the second and other courses are laid. a

It will be noted that the brick laying mechanism always acts intimedrelationship with the gear for traversin the brick laying mechanismand for traversing the apparatus bodily on its rails, the. clutches"being capable of engagement only at one point perrevolution of theircorresponding clutch members; i

The bricksare fed to the receptacle'9 by an attendant whostands on aplatform 99, Figure '12. In order to accelerate the process of buildingmeans are provided whereby the attendant is automatically supplied withbricks, as indicated diagrammatically, Figure l.

V This may beaccomplished by suspending a V cage 99 at the, outer sideof each of the upright structures A, A the ropes supporting the cagepassing over pulleys at the upper ends of said structures, pulleyscarried by the structures B and then connected to carriage 6. i Thearrangement is such that as the said carriage with brick layingmechanism traverses structure B one of said cages is lowered to filledwith bricks While the other one is raised so that when theattendantreachesthe end of his travel he is provided with'a cage ofbricks to feed to tl'ie'bricklaying device.

As thecross member is raised the ropes automatically become shortenedandthey are attached on roller having driving gear by which they arerotated to allow of the slack being from the bands and deposits same onthewall.

Secured to projecting brackets 82 onthe frame is a cross shaft 83 onwhich are secured an arm 84 and two arms 85 one ateach side of the mchine. Arm 81 carries a roller 84 at its lower end, while the extremityof each 7 I of the arms 85 is connected bv means of a rod 86 to a lever87 pivoted at 88 and carrying a roller and, bevelling or skimming bar89. A'

helical spring 90 is connectedto the levers 87 and frame.

The action of such device is as follows: After each brick has beenlaidand the machine has traversed one third the length of a brick the camthrough the aforesaid mechanism permits the scraper to be moved to-Vwards the last laidbrick under the action of the spring 90, some mortarbeing scraped up in its travel and deposited against the exposed end ofthe brick. Further said bar pushes the bricks up against the adjacentbrick thereby consolidating. the wall being built.

As shown in Figures 8 and 8 guiding arms' 91 are carried by the bricklaying "apparatus g and which serve to ensure that each brick is broughtinto alignment; as the courses are laid. To permit the brick layingapparatus to be moved through an angle of 90 as aforesaid said guidearms must be raised clear of the wall. This is accomplished'by mountingthe arms on the pivoted parallel arms 92 and connecting same to avertical rod 93 by raising which the guide arms are likewise raised soas to permit the partial rotation of the brick V laying device. It isdesirable that the mortar in the tank be kept in a state of agitation.

In the arrangement shown this is effected by means of a stirring blade94 (see Fig 5) carried by arms 94 on a crossbar keyed to a shaft 94" onwhich is secured an arm 95 (see also Fig. 3)- the latter being connectedby means of a rod. 96 with an eccentric 97 onthe shaft of roller 74:. V

By such means the mortar is kept in a'contmual state of agitationwhenthe apparatus is in operation.

g The structure by which the brick layingapparatus is supported may bemodified. For

example at each side of the 'buildingt o be built two verticalstructures may be erected each provided with horizontally extendingstructures arran ed parallel to each other and to two of the four wallsto be built. A cross member extends between and joins the horizont allyextending structures and is arranged to travel along same.
